What is this test?
Low-dose CT (Computed Tomography) scan of the lungs is a specialized imaging technique that uses a reduced amount of X-ray radiation to capture detailed, cross-sectional images of lung tissue. This scan is optimized to minimize radiation exposure while still providing clear images to screen for lung abnormalities, especially early-stage lung cancer.
What is it used for?

• Lung cancer screening, particularly for early detection of lung nodules or masses before symptoms appear
• Identifying small nodules, lung scarring, or other chronic lung conditions such as emphysema or fibrosis
• Monitoring individuals at high risk of lung disease to enable timely interventions
• Helping guide further diagnostic testing if abnormalities are found

Who should get this test?

• Current or former smokers aged 50 years and older with a significant smoking history (usually 20 pack-years or more)
• Individuals with chronic exposure to lung irritants such as asbestos or radon
• Patients with a family history of lung cancer or other risk factors for lung disease
• People with unexplained respiratory symptoms who require detailed lung assessment

Preparation Required:

• No special preparation or fasting needed
• Remove any metal objects from the chest area, such as jewelry or clothing with zippers, to avoid image artifacts

How is the procedure performed?
The procedure is quick and painless, typically lasting only 5 to 10 minutes. The patient lies on a motorized table that slides through the CT scanner, which takes multiple low-dose X-ray images of the lungs from various angles. Patients are usually asked to hold their breath briefly to reduce motion blur and ensure sharp images.
Risks & Safety:
This low-dose CT scan uses a significantly lower radiation dose compared to standard CT scans, reducing potential risks while maintaining image quality. Although the radiation exposure is minimal, it is still important to weigh the benefits against risks, especially for repeated scans. There is no use of contrast dye, so allergic reactions are not a concern.
Results:
A radiologist carefully examines the images to detect any lung nodules, masses, or structural abnormalities. Findings are reported with recommendations for follow-up, which may include additional imaging or biopsy if suspicious lesions are identified.
Short Statement:
A low-radiation CT scan tailored to screen the lungs for early signs of cancer, nodules, or chronic lung disease — perfect for smokers or those at elevated risk.
